Amino sugars. Glucosamine and galactosamine were determined on the Phoenix amino acid analyzer employing Beckman resins. Samples were hydrolyzed with 2 N HC1 for 1, 2, 5, and 10 hours in sealed tubes at 105 ± 2° C. Dry weights of samples were determined on a Mettler balance of material dried by lyophilization. Several samples of multivalent and univalent Lytechinns fertilizins were concen- trated by dialysis against Aquacide (Cal. Biochem.).. FIGURE 3. Sedimentation pattern of multivalent and hydrogen peroxide formed univalent fertilizins. Speed was 47,660 rpm at 10° C. Time illustrated is 64 minutes after speed was attained. Bar angle of 45°.
